To t/Z' 'who/rait may concern.:

A Be it known that 1, OWEN W. PFoUTs, a citizen or"v the United States,residing at Alliance, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in the Purification andDisposal of Sewage; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe annexed drawings, makinga part of this specification, and to thecharacters of reference marked thereon, in which- Figure -1 is a topView., Fig. 2 is a traneverse section on line c c, Fig. 1. Fig. 3 is anenlarged View of one ofthe lowervalves. Fig. 4 is an edge view of theoutlet-pipe. fFig. 5

The present invention has relation to the purification and disposal ofsewage; and it consists iny the novel construction and arrangementhereinafter described, and particularly pointed out in the claims.

Similar characters of reference indicate corresponding parts iu all thefigures of the drawings.

In the accompanying drawings, 1 represents the septic or receiving tank,which is fpreferably formed circularl and' of any size, reference beinghad to the amount ofl sewage to be operated upon. The bottom 2 of theseptictank 1 is concaved, the lowest point of said bottom being locatedat or about the vertical center of said tank and is so located for lthepurpose 'of bringing the sediment toward the center of said tank.

For the purpose of giving the contents off the septic-tank a whirling orrotary motion the delivery end of the inlet-pipe o is located at-oneside of the vertical center and adjacent to inner periphery or wall ofsaid septic-tank.

Fi'g. 8 is a transverse section on line pipe' 3 is 'reduced in size, bywhich arrangement-a sufcient amount of `back force will be'produced ,togive the-desired amount .0f pressure tothe sewage-.f j f The maininlet-pipe 4 is' formed offlarge'r diameter than that of the pipe, Asaidpipe be ing connected in the ordinary manner at its outer endor'conneetion.

. 60 For the purpose of providing for conveying the full capacity ofthe'mletpipe' 4 to v the4 septic-tank 1 the overilowpipe5 is provided,

by which arrangement there will be no back pressure-in the pipe 4. In th'drawi n gs I have shown one'overiiowpipe; but it will be understoodthat more than one maybe provided, if desired, as the only objectdesigned' isreprosa4'1emeuiiieientoa pacity to carry or convey all ofthe sewage'at all times.

By imparting rotary movement to the conpoint on said b'dttom.

ktents of the septic-tank'l the heavier and more solid material or, inother words, the 75 For the purpose of con veying vthe sludge from 4thesedimentation-chamber 15' to the well 8 the pipe 7 is'provided, whichpipe leads from the bottom of the 'chamber 15 to' said sludgewell, whichwell may be located at any desired point, reference being hadv to theproper conveyance of thesludge.

For the purpose of removing the accumu-` lation of the sludge or foran'y other purpose a valve, such as 9, is provided, which .valve is tobe operated by arsuitabl'e rod 10, it of. course being understood thatthe valve 9 is to be providedrwith a suitable valve-seat, formed uponthe upper-end of the elbow I1.1

or its equivalent.

Within the septic-.tahiti iszlocated the'v apertures or openings 13,said openings be# ing preferablyarrangedas illustrated in F1gs.4,5,a-nd6.

vertical outlet-pi pe 12, said outlet-pipe being'. lprovided at its topend or portion with the For the purpose of removing thefs'ewage from theseptic-tank 1 ata point bet-Ween the 'top and bottom of the sewagethe'outlet-pipe 1'2 is formed of such a. heightthat its upper end willbe below the upper sewage-line, or, in

otherr words, belet;7 the top ofthe sewage.

It will be understood that the outletpipel 12 should be formed of such asize that it will provide an outlet of about the' same capacity as thatof the inlet-pipe 3, by which arrangement the amount 'of sewage willremain about the same at alltimes. f

At the bottom or lower end of the vertical outlet-pipe 12 is connectedthe pipe lehwhich pipe leads to the bottom or lower portion of thesedimentation-chamber l5.

When it is desired to remove the sewage from the septic-tank at a pointbelow the top or upper end of the outlet-pipe 12, the valve 16 isopened,thereby allowingr the sewage to be removed to a point level withthe valve 16, said valve being located upon the top or upper end of' theelbow 17, said elbow being connected to the vertical feed-pipe 12 at orabout midway between its top and lower end,

substantially as illustrated in Fig. `6. It will be understood that thesewage will find the water-line vwith the septic-tank l, and at or aboutthe normal water-line of said tank and to one side of thesedimentation-chamberare located or formed the aeration steps or falls18, said falls being located and arranged substantially as shown in thedrawings. lVhen the sewage has passed over the falls 18, it is conveyed'to the oxidizing-tank 19 through the valves 20 and 21. One of saidvalves may be closed, thereby conveying all of the sew-A ,age to one ofthe oxidizing-tanks 19, or both valves may be'open, as desired,l thisbeing i simply a question. of judgment.

the p The door of the oxidizing-tank 19 is composed of hollowbuilding-'blocks placed in position with loose joints and on the top ofthe cement bottom 22; The oxidizing-tanklQ is provided with a tr nsversepartition 23, which partition exten s from the top of the hollowHooi-,said hollow iloor passing under the partition, as illustrated inFig. 6. It will be understood that as the sewage enters theoxidizing-tank it will pass downward and nd its way into the hollowfloor or buildingblocks and from thence under the partition 23 andupward upon the opposite side of the partition 23 and thence into thechannel 24, said channel being located upon the top of theoxidizingvtank 19 at its outer or deiivery end, from --whence it fallsinto the receptacle 25, and

said' receptacle it is conveyed through e 26 and onto the trough-tiles2,7,

` vwhich trough-tiles are formed in'sections and the sections looselyjoined together, said trough-tiles being located on the top of thefiltering material located in the sand filters 28, which operation iscontinued through filters 29, two filters being shown; but it will beunderstood that any desired number may be employed'to produce properfiltration.

The oxidizing-tank 19 should be tilled with coarse cinders, coke, orcoarse gravel or any like material, as it will be understood that rthematerial used tolill the oxidizing-tank "fshould be coarse, so thatthespaces between the material used to fill the oxidizing-tankoxidizing-tank 19,

When it is desired to remove the sewage from the oxidizing-tank 19 andoxidize the organic material adhering tothe filtering material, thevalves 20 and 2l are closed or one of said valves closed, referencebeing had to the tank desired to be operated upon, and the outlet-valves30 and 31 opened, it being understood that if the valve 2l. isclosedthen valve 30 is to be open, by which varrangement all of theliquid is conveyed through the hollow door and to the chamber 25 andthence through the pipes 26 and 27 and onto the filters 28 and 29.

In the drawings I have shown two sets of oxidizing tanks and filters andthe necessary pipes and valves belonging thereto, which may be usedalternately,I if desired. It will be understood that any desired numberof oxidizing tanks and filters may be located side by side as the twoare arranged. h

When it is desired to emptyand clean the septic and sedimentation tanks,the valve 32 is open and valve 16 is raised lor opened, at which timethe water from the septic-tank is conveyed 4into the sedimentation-tan kand through .the pipe and on to the oxidizingtanks and thence throughthe filters.

When it is desired to remove the sludge from theseptic-tank and thesedimentationtank, the valves 9 and B-L are open, thereby allowing thesludge to pass through the pipe 7 and be conveyed to the sl udgc-well 8or any other desired point. f r

It wilLbe understood that by providing the open tiles 27 and looselyconnecting them together and locating said tile upon the top or upperside of the filters the sewage will be -distributed over said filters,thereby causing the sewage to become distributed, thereby producing abetter filtration.

It will be understood that more than one inlet-pipe, such as 3, may beemployed, and they may be located upon opposite sides of theseptic-tank, it being understood that the flow of sewage should be inopposite directions, if in the event inlet-pipes are located uponopposite sides, by which arrangement the circular motion given to thesewage will not be counterba'lanced. lt will also be un derstood thatafter the sewage has been passed through the'oxidizing-'tanks andfiltered it is t0 be conveyed in any well-known manner to a suitablewatercourse, such as A.
